Measurement of mood and affect in schizophrenic inpatients
TJ Craig, MA Richardson, R Pass and Z Bregman
Ratings of mood and affect using the Brief Psychiatric Rating Scale (BPRS),
the Hamilton Rating Scale for Depression, the Center for Epidemiologic
Studies Depression Scale (CES-D), and an affective flattening scale in 32
male schizophrenic inpatients revealed high total scale reliability but
lower intra-item reliability, especially for specific depression items.
Interscale correlations suggested several dimensions of mood and affect:
anxiety-depression (psychological dysphoria, motor activation, and somatic
symptoms), retardation-affective blunting, thought disturbance, and
hostility- suspiciousness. Correlation with a rating of extrapyramidal
symptoms suggested an association with the presence of depressive symptoms.
These results suggest that although adequate total scale reliability was
obtained, these indexes of depression may measure different dimensions in
schizophrenic patients than they do in patients with affective disorders.
